$x^{\frac{- 9}{8}}$

Step 1

Move the negative in front of the fraction.

$x^{- \frac{9}{8}}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{x^{\frac{9}{8}}}$

Step 3

Apply the rule $x^{\frac{m}{n}} = \sqrt[n]{x^{m}}$ to rewrite the exponentiation as a radical.

$\frac{1}{\sqrt[8]{x^{9}}}$
